How to choose Shaft coupling

Points to check when selecting, with the values for this product (AL-075).

  1. 1. Allow Margin for Rated Torque

    This product: Continuous torque 5 N·m

    Select a size whose continuous operating torque is equal to or greater than the load torque transmitted during continuous operation. Check by multiplying the motor's rated torque by a factor corresponding to the frequency of starts and stops and load fluctuations. Listed products have a rated torque of 0.5 to 150 N·m.

  2. 2. Verify Peak Torque at Startup Against Maximum Allowable Torque

    This product: Maximum Allowable Torque 15 N·m

    Large instantaneous torques occur during rapid acceleration and deceleration of servo motors, startup, and emergency stops. Confirm that these peak values do not exceed the maximum allowable torque. For taper clamping elements, this value serves as a guide to the torque the clamp can hold.

  3. 3. Match Shaft Diameter to Machinable Bore Diameter

    This product: Maximum hole diameter d 26 mm

    Confirm that the driving and driven shaft diameters fall within the applicable shaft diameter range. When machining pilot-bored products, confirm the bore is within the maximum bore diameter d. If the two shaft diameters differ, check that both hubs have matching bores.

  4. 4. Do Not Exceed Maximum Rotational Speed

    This product: Maximum Rotational Speed 7000 min-1

    Confirm that the maximum operating speed is at or below the coupling's maximum rotational speed. Larger outer diameters are more susceptible to centrifugal force, and the allowable speed tends to be lower. Listed products range from 3600 to 18000 min-1.

  5. 5. Check Allowable Mounting Misalignment

    This product: Maximum permissible eccentricity 0.2 mm

    Confirm that the parallel misalignment expected from assembly accuracy is within the maximum allowable eccentricity (0.1 to 0.4 mm for listed products). Compare angular misalignment against the maximum allowable declination (0.5 to 1°). Exceeding these allowances causes early wear of the buffer and increased bearing load.

  6. 6. Select Hub Material and Inertia for Responsiveness

    This product: Moment of inertia 5.36×10-5 kg·m²

    Aluminum alloy hubs are lightweight, low-inertia, and less likely to impair the responsiveness of servo and stepping motors. Cast iron hubs have high inertia and tend to provide stable rotation, and nickel-plated products offer corrosion resistance. In environments requiring rust prevention, also check whether surface treatment is applied.
